One Channel Speech Controller

5.7 PWM Output

An PWM circuit is built-in SNC15040. The maximum resolution of PWM is 8 bits.

Two huge output stage circuits are designed in SNC15040. With this advanced

circuit, the chip is capable of driving speaker directly without external transistors.

5.8 Watch Dog Timer

SNC15040 built an internal WDT (Watch Dog Timer). This Watchdog timer would

issue resets signal to this chip if it is not cleared before reaching terminal count (1sec).

The watchdog timer is enabled at reset and cannot be disabled.

5.9 IR Function

P23 can be modulated with 38.5KHz square wave before sent out to P23 pin.

The IR signal can be achieved by this modulated signal.
